ohlinux.com is a personal blog maintained by independent developer qeandzc, focused on low-level Linux kernel technologies. Its core content centers on Linux kernel memory management and GPU memory management: it tracks the latest submission updates from the kernel community, and also publishes systematic, in-depth source code analysis articles. It is one of the few technical sites in China that focuses deeply on the Linux kernel memory space.
The site's biggest strength is the depth of its content. Its popular series on memcg memory control groups breaks down the topic from design evolution and core data structures to code execution flow, all analyzed against the latest mainline kernel source code. The details are comprehensive, the logic is clear, and it even explains low-level design choices like data structure alignment and atomic operation optimizations, making it a very valuable reference for practical development and debugging.
The content layout is clean, there are no distracting commercial ads, so the reading experience is uninterrupted. However, limited by its positioning as a personal site, it currently only covers memory management-related topics. Updates depend entirely on the author's personal time, so the frequency is inconsistent, and there is no section for user comments or interaction. The content also has a relatively high technical threshold, so it is better suited for developers with a foundational background — absolute beginners will likely find it very difficult to follow.
The site is currently directly accessible from within China, and all content is completely free and open to the public. It is an excellent learning reference for Linux kernel developers, operating systems students, and low-level performance optimization engineers. If you are currently working on problems like memory reclamation, cgroup memory control, or memory leak debugging, the systematic analysis here will help you sort out the kernel's design logic clearly.
